How to adjust the burner of rotary kiln
2. Adjust according to the kiln shell. The normal thickness of the kiln shell is 200-300mm, the surface is flat, the length of the main kiln shell is 13-18m, and the length of the by-kiln shell is 18-20m. The burner must be moved every shift to make the by-kiln shell fall and long dynamic repeating process and prevent the ring forming. 3.

Refractory Lining In Cement Rotary Kiln
Refractory lining in cement rotary kiln's heating and cooling system is a key. The kiln-lined alkaline refractory bricks are the most easy to bricks to crack and peel, and their service life is also the shortest because they have the largest thermal expansion coefficient and poor thermal stability, but they are used in the highest temperature zone in kiln.
